CT的基本原理是由投影重建图像,关于重建算法,提出了许多算法,其大致可以分为两大类：一类称为解析法,一类是迭代法。其中在常用的迭代重建算法即代数重建技术[1,2]（Algebraic Reconstruction Technique简称为ART）ART算法中,很多因素影响图像重建的质量和效果,本文进行了一些参数仿真分析,成像效果比较。

The basic principle of CT reconstruction by the projection image reconstruction algorithm,many algorithms can be roughly divided into two categories：a category known as the analytical method,an iterative method.In the iterative reconstruction algorithm,algebraic reconstruction technique[1,2]（Algebraic Reconstruction Technique referred to as ART）,ART algorithm, many factors affect the quality and effectiveness of the image reconstruction,the paper some of the parameters of simulation analysis,the imaging results.
